I´ve downloaded and installed the Dynamic Lighting mod in P3D V4.1 for EGPF, Dynamic Lighting is also enabled in the sim settings. However, I am not seeing any difference. I´m sure I´ve not done something correctly but cannot figure it out. Screen shot attached.

It is different. Your ground is now dark, as you have install the MOD which removes the "baked" in ground lights, but you dont have the dynamic lights on the ground which replace it, probably because you have not turn it on in your P3D Lighting settings?

Do you mean "choose p3D lights" in he UK2000 scenery config options or do you mean having Dynamic Lighting enabled in the Sim (which it is)

I´ve downloaded the latest Library file, V3.48 and can also confirm that the four fx files are in the effects folder. That has solved the problem and also noted no measurable performance loss with FPS - brilliant - thanks Gary. Merry Christmas!
